IMPROVEMENT IN METHODS 'OF DRYING NAPPED CLOTH.

Specification forming part of Letters Patent No. 123,768, dated February20, 18.72.

SPECIFICATION. To all whom 'it may concern:

Be it known that I, WARREN GHAPIN, of

Sta-ordsville, Tolland county, State of Connecticut, have invented an Improved Method of Drying Napped Cloth,7 of which the following is a specication:

Nature and Objects of the Intention.

Description of the Drawing.

Figure I shows a plan view of a frame holding the roll and cloth in position upon it to be revolved. Fig. II shows an end view of the same frame with the cloth in position..

l General Description.

A is the roll, upon which the cloth B is wound in the napping-machine after having the nap formed upon it under water, and to extract the water (the next process in the Inanfactnre of the cloth) I take the roll A having the cloth B, usually in length from twenty-live to thirty yards, although the amount of cloth upon the roll does not affect the principle of the invention, and remove it from its position in the napping-machineto place it in a frame similar to that shown in the drawing, which may form part of the napping-machine or be a separate and independent machine of itself its object being only to ai'ord bearings to two centers, o and d, that come against the ends of the roll A, the one, c, clutching one end of the roll and bearing a pulley, f, through which, by a belt, g, the motion is transmitted to the roll and cloth, while the other, d, is a movable center for the purpose oi en ablin g the roll to be removed or secured. The roll and cloth, when thus placed, are rotated rapidly say about eight hundred revolutions per minnte-and .the centrifugal force, together with the evaporation caused by such rapid motion, .carries off all of the free water in the cloth and leaves it in good condition for drying.

In the ordinary method, consstin g of removing the cloth saturated withwater from the roll of the napping-machine and placing it, folded or otherwise creased, within the extractor, the nap is disturbed and the colors, wherever the cloth is creased or bent, run or become varied in intensity. 'lhe extractor is, moreover, an lexpensive piece of machinery, and generally requires much more power to rotate it effectually than is required to perform all of the rest of the mechanical operations connected with the manufacture of the cloth; while, by my method, the cloth is undisturbed upon the roll upon which it was wound in the nap-- ping-machine, it being only necessary to pin the end of the -piece of the cloth to the rest upon the roll to prevent it from coming oft' in the revolution. All injury to the nap or to the body of the cloth by the alteration in the colors is avoided; and I am able to dispense with the heavy expensive extractor and the additional power necessary to run it.

Now, havingv described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The method of extracting the water from the cloth after it has been napped by revolving it upon a spindle and while in the roll, substan, tially as hereinbefore specified.
